Atropine,
as the most active principle in Belladonna, produces, as
we should expect, most of the characteristic effects of that drug; but at the same time the
two are not identical. Atrop. produces hyperæsthesia of
the sensory nerves. The most numerous symptoms have been observed in the eyes. All kinds of
illusions of vision. Everything appears large. Motes over everything. I once cured with it a
lady who had an appearance of shadows passing over whatever she looked at. It has shown an
affinity for the pancreas, which relates it to Iod., Kali iod., and Iris. A case
of chronic wryneck, of three years' standing, was relieved and finally cured within two
weeks by injections of 1/120 into the platysma, the dose being increased up to 1/20th. This
was in old-school practice. It has caused difficulty of speech: frequent stuttering,
especially at words difficult to pronounce; articulation indistinct, rapid and chattering.
